Wiki-UX / Dynamic Root Disk
Category:Dynamic Root Disk
Dynamic Root Disk is used to perform software maintenance and recovery on an HP-UX Operating Environment with minimum system downtime. Dynamic Root Disk (DRD) provides customers the ability to clone an HP-UX system image to an inactive disk. Also:
Another typical use is to migrate the bootable drive to a larger hard drive(s) avoiding LVM Physical Volume restrictions.
Using DRD commands, you can apply patches and make other modifications to the cloned system image without affecting the active system image.
Hewlett-Packard developed DRD to minimize the usual maintenance window during which you shut down the system to install patches. With DRD the system keeps running while you clone the system image and apply patches to the cloned image. DRD tools can manage the two system images simultaneously. DRD also provides a fail safe mechanism for returning the system to its original state, if necessary.
